AI and chatbot-supported interventions for pediatric physical activity and obesity-related lifestyle behaviors show mixed effectiveness, with 4 of 8 studies reporting significant improvements in physical activity or fitness outcomes.
This scoping review of 14 studies found that AI-enabled chatbot interventions for pediatric physical activity and obesity-related behaviors are a rapidly emerging field, with most studies published since 2023. Among 8 studies reporting direct physical activity or fitness outcomes, 4 showed significant improvement, 2 found no significant change, and 2 reported mixed or indirect findings. Family involvement was present in 71.4% of studies, and feasibility and acceptability were generally favorable.

The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸AI and Chatbot-Supported Interventions for Physical Activity and Obesity-Related Lifestyle Behaviors: Scoping Review With Attention to Family Involvement. (JMIR pediatrics and parenting, 2026) — This scoping review of 14 studies found that AI-enabled chatbot interventions for pediatric physical activity and obesity-related behaviors are a rapidly emerging field, with most studies published since 2023. Among 8 studies reporting direct physical activity or fitness outcomes, 4 showed significant improvement, 2 found no significant change, and 2 reported mixed or indirect findings. Family involvement was present in 71.4% of studies, and feasibility and acceptability were generally favorable.
How It Works
The proposed biological pathway:
- ▸AI chatbot provides personalized feedback and self-monitoring tools
- ▸Users engage with the system through natural language interactions
- ▸System delivers educational content and behavior change support
- ▸Result: Mixed improvements in physical activity and lifestyle outcomes
Who Might Benefit
Evidence fit by population:
- ▸Children, adolescents, and families
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Only 14 studies met inclusion criteria, indicating a limited evidence base
- ▸Cultural tailoring was reported in only one study, limiting generalizability
- ▸Family involvement varied considerably and was not clearly conceptualized or evaluated
